Glossary/Abbreviations
ISS Integrated Sensor Suite: This is the Davis term for the main sensor assembly and sensor interface
module (SIM board) which sits outside in the weather and actually generates the raw weather readings. On
a standard Vue or VP2 system, the weather station will consist of two components: the ISS and the display
console. On a VP2 system the anemometer is also included when a new ISS, which is available as a
separate spare, is purchased.
SIM board This is the Sensor Interface Module – the circuit board that is a key part of the ISS. Each of the
individual outside sensors plugs into the SIM board, whose circuitry processes the raw readings and
transmits the data in packets back to the console by cable or by wireless according to the type of station.
VP1 The abbreviation commonly given to the original Vantage Pro weather station manufactured by Davis
from 2000-2004. The VP1 was never known as such during its lifetime, being referred to as simply a VP
station, but with the advent of the new generation of VP2 stations there was a need to distinguish old and
new versions, hence VP1 and VP2. Note that most of the parts of VP1 and VP2 stations are not compatible
with one another (because the communications protocol is incompatible), although a few of the basic
sensors such as anemometer and rain gauge are interchangeable.
VP2 The current generation of Davis Vantage Pro 2 weather stations.
WMII The Davis Weather Monitor II stations, which were the mainstream Davis stations before the VP1
stations were launched and whose manufacture ended about 2005.
WWIII The Davis Weather Wizard III stations, which were a more limited companion product to the WMII
stations and of the same era.
